Nutritional supplements offered here are in dosages recommended by the ReCODE Protocol. Our aim is to provide the best quality and low cost. We first look for a *CL Approved product, tested for purity and accurate labeling and Approved by ConsumerLab.com, an independent laboratory whose test results are available to the public. If no *CL Approved product is found, we offer a supplement by a company that produces other supplements that have been so tested and Approved. We receive a commission of 4.5% of the price of products purchased from Amazon from this website, but there is no incentive for us to prefer any company over any other.
